Pleasing results & hit 60 mpg again.

Thanx, Darin,

I took your advice & did it without doing another set of "A" tests beforehand (or after, because I was so pleased, I didn't wanna remove it!!!) The weather was similar to the way it was when I did the initial "A" tests the other day, and as you suggested, don't think I need to "prove" it in rigorous testing - - - - I know it works!!! (see thumbnail below)

Revisiting my initial "to do list", starting to have some progress.

1) Air up the tires to? 155-80/13 Can they handle 60, I wonder?

2) Front grille block with black duct tape - nicer one later

>>> VERY pleased with this. Gained 2.467 MPG; from 46.95 to 49.41 at 55 MPH <<<

3) Fuel injector kill switch for better EOC-ing
4) Hand throttle control, so I can drive long distances easier
5) Rear wheel/4-wheel alignment. Outsides of rear tires are wearing badly
6) Engine/oil pan heater. Not super-cheap, but it's winter & I want MPGs!
7) Rear fender skirts - cardboard first for A-B-A testing, then nicer - maybe
8) Full belly pan
9) Front & maybe rear wheel covers and/or fairings/spats
10) Kamm-back/partial boattail
11) At some point by about now, I'll need new tires - will try to find LRR
12) When the next oil change is due, go to Mobil-1, 0w20
Oh, I was so pleased with the grille block results I decided to do a pair of runs (northbound & southbound) at lower speeds. I did it between 35 and 40 MPH and averaged 61.95 MPG according to the ScanGauge. I almost did another one at between 40 and 45 mph to see if I could hit 60 mpg at that speed, but didn't due to the time.

But this time, I'm much more confident than I was with my original 60+ mpg result, because the ScanGauge has been re-calibrated a couple times, and I think I'm finally getting it "zeroed-in" (adjustments are getting much smaller)
